There Was No Calendar on Android TV — From a Family App to Worldwide Use

Panda Calendar started with a small frustration.

We have an Android TV in our living room. We used it for news and videos, but one day my wife said "it would be nice to see this week's schedule on the TV."

"That makes sense," I thought, so I searched Google Play — and there were almost no calendar apps available for Android TV. The ones that existed were phone apps repurposed for TV, not designed for remote control, with text too small to read from across the room.

"If it doesn't exist, I'll build it" — that's how it started.

At First, the Goal Was Just "Something That Works at Home"

I'd built apps before, so it wasn't technically impossible. But the original goal was simply "get the TV to a state where my wife can check Google Calendar on it." No grand plan.

The first version was pretty bare-bones. Calendar displays, events visible, operable by remote. That was it.

But when I showed my wife, the first thing she said was "make the icon cuter." She likes drawing, and she put forward her own design proposal. "How about a panda?" — those words decided both the name and the character of this app.

The "Judge a Book by Its Cover" Strategy — My Wife's Intuition

My wife drew all the icon designs herself. She says "if it's cute, people will download it," and that turned out to be literally true.

In the first few weeks after releasing the app, downloads grew at an unexpected pace — from Japan, but also from abroad. I think more people downloaded it because they thought the icon was cute than because they read the feature descriptions.

My wife looked at those results and said "see, I told you." Honestly, she was right.

My Son's Ideas Kept Adding Features

Some time after releasing the app, my son said "add weather too." He was in elementary school at the time, and the idea seemed to be that if the calendar showed the weather, field trip days would be more exciting.

When I implemented it, it was well received. Reviews requesting "weather forecast in the calendar" started coming in, and it's now one of the main features.

The stamp feature also came from a family conversation: "it would be fun to stick pictures on the calendar." Our development meetings happen at the dinner table.

Before I Knew It, It Was Reaching the World

Google Calendar is used worldwide. Android TV is also spreading globally, not just in Japan. The desire to "use Google Calendar on TV" existed not just in Japan, but around the world.

The reason I added multilingual support was that I started receiving requests from overseas users: "please support my language." It now supports 40 languages.

An app that started from a small frustration in our family's living room is now reaching living rooms around the world. Honestly, that still feels a little surreal.

We'll Keep Building What Our Family Wants to Use

The development philosophy hasn't changed from the beginning: "build things that are useful when we use them at home."

Feature ideas still often come from the family. My wife talks about design; my son suggests "it would be nice to have a feature like this." Not everything gets adopted, but it's important input when thinking about direction.

I want to keep building an app that our family — and families around the world — want to use.
